Anyone notice that the Rick in the yellow shirt is the one that gets vaporized? Maybe they don't care (the other ricks dont have any reaction to this) because he's just another dispendable Morty in their eyes. Because, yakno, most Ricks from other dimentions don't care about Mortys... just making an observation based on the whole t-shirt color motif the show has had going on like in the Tiny Rick episode.
